Pre-Interview Cheatsheet
Petroleum Engineer — Confidence Cheatsheet
A printable, focused refresher tuned for Petroleum Engineer. Open the sections that matter to you and walk in confident.
Tuned for Petroleum Engineer · Engineering & Architecture > Petroleum / EnergyRefresh Right Now The 60-second mental warm-up before you start.
- Know reservoir, drilling, production, well completion, fluids, pressure, flow assurance and safety.
- Understand porosity, permeability, reservoir pressure, well control, mud weight, inflow/outflow and production optimization.
- Refresh pore pressure/fracture gradient, casing, BOP, kick, EOR, decline curves and NPV of field development.
- Strong answers show technical judgment plus safety and economics.
- Be ready to discuss well-control risk at a high level.
Core Vocabulary Terms interviewers expect you to use precisely.
- Porosity: fraction of rock volume that can store fluids.
- Permeability: ability of rock to transmit fluids.
- Mud weight: drilling fluid density controlling wellbore pressure.
- Kick: influx of formation fluid into wellbore.
- Flow assurance: preventing hydrate, wax, scale, slugging and blockage issues.
Formulas & Frameworks The mental models that organise your answers.
- Well planning: geology, pressure window, trajectory, casing, mud, BOP, risks, contingency.
- Production optimization: reservoir, wellbore, surface constraints, economics.
- Safety: barriers, well control, procedures, monitoring, emergency response.
- Economics: production forecast, capex, opex, price, NPV, risk.
Likely Interview Prompts Questions you should be ready for.
- What is porosity vs permeability?
- Explain mud weight and well control.
- How do you optimize production?
- What are drilling risks?
- How do safety and economics interact?
Red Flags To Avoid Common answers that lose interviews.
- Ignoring well control/barriers.
- Treating reservoir and wellbore separately.
- No economics awareness.
- Overconfidence with uncertain subsurface data.
- Poor safety language.
What Sets You Apart Signals that move you from competent to memorable.
- Integrates reservoir, drilling, production and economics.
- Strong barrier mindset.
- Handles uncertainty quantitatively.
- Communicates risk clearly.
30-Second Confidence Reset Anchor sentence to read just before you walk in.
Petroleum answers need safety and integration: reservoir uncertainty, pressure control, production constraints, barriers and economics.
